POWER-TRANSMITTING MECHANISM.

To all whom it may 60716677 Be it known that I, OSCAR Knox, a citizen of the United States, and a resident of New York, county and State of New York, have invented a certain new and useful Improvement in Power-Transmitting Mechanism, of which the following is a full, clear, and exact specification.

This invention relates more particularly to a mechanism adapted to be used for utilizing with little or no loss the power of a motive agent for operating machinery, or for other purposes.

My invention has for its object primarily to provide a form of power transmitting mechanism designed to be employed for receiving compressed air, steam, or other m0- tive agent from a suitable source of supply and utilizing the power practically without loss or exhaust for revolving a drive shaft to operate machinery or other appliances with highest efficiency. This is accomplished mainly through the medium of a rotary cylinder for receiving the motive agent under pressure. The receiving cylinder has one or a plurality of auxiliary cylinders in each of which is a piston connected by a crank to the drive shaft. The auxiliary cylinders are positioned at an angle so that the pistons thereof will receive a maximum of pressure of the motive agent when the rotary cylinder is revolved and the resistance thereby created by reason of the pistons tending to be unseated in the auxiliary cylinders by the revolutions of the receiving cylinder will result in sutficient leverage being transmitted upon the crank of each piston to revolve the drive shaft at the same speed as the receiving cylinder is driven.

A further object of the invention is to provide a power transmitting mechanism which is simple in construction, which may be made in any desired size, and its parts are so formed as to be readily assembled or repaired in case of damage thereto.

A practical embodiment of the invention is represented in the accompanying drawing forming a part of this specification in which similar characters of reference indicate cor responding parts in all the views, the said invention being more fully described hereinafter and then pointed out in the appended claims.

In the drawing Figure 1, is a side elevation, partly in section, of one form of my Specification of Letters Patent.

Application filed July 19, 1911.

Patented Jan. 27, 1914. Serial No. 639,427.

power transmitting mechanism embodying my invention. Fig. 2 is a section taken on the line IIII of Fig. 1, and Fig. 3 is a section on the line III-III of Fig. 1.

The power transmitting mechanism 10 has a hollow shaft 11 which is journaled in bearings provided in standards, as 12 and 13, or may be rotatably held in any suitable frame. Upon the shaft 11 and between the standards 12 and 13 is loosely held a horizontally disposed cylindrical receiving cylinder 14 of any desired length and diameter, and the interior of said cylinder is in communication with the passage through the hollow shaft by means of one or a plurality of feed openings or intake ports 15. At one endof the receiving cylinder 14 is an opening or vent 16 through which access to the interior of said cylinder may be obtained in case of cleaning or repairing being required, and said opening may be closed by a cap 17. Upon a suitable number of lugs or projections, as 18, provided upon the opposite end of the receiving cylinder 14 is fastened by screw bolts, or the like, a gear wheel 19, and meshing with said gear wheel is a pinion or smaller gear wheel 20 which is keyed upon the drive shaft of any preferred form of engine, or by an electric motor 21, as shown, which is adapted to revolve the receiving cylinder 14 at a desired speed.

In the wall of the receiving cylinder 14 may be one or a plurality of auxiliary cylinders 22, each of which has an annular flange 23 upon its end exteriorly of said receiving cylinder, and upon the annular flange is held a plate 24 whereby a piston seat or head is provided for each of the auxiliary cylinders. The auxiliary cylinders 22 are preferably arranged at equally spaced intervals around the axis of the receiving cylinder 14, and preferably the axes of the auxiliary cylinders are arranged coincident with chords that subtend an angle of ninety degrees with reference to a cross section of the receiving cylinder 14.

As a means to convey the power from the receiving cylinder 14 to the hollow shaft 11, in each of the auxiliary cylinders 22 is a piston 26. To each of the pistons 26 is connected one end of a crank or lever 27, and the opposite end of said crank is rigidly fastened to the hollow shaft 11. The pistons 26 are arranged so as to be normally seated against the heads of the auxiliary cylinders and by this arrangement each of the cranks or levers 27 will receive the great est amount of leverage when the mechanism is operated.

In order to supply the receiving cylinder 1a with a motive agent, such as compressed air, steam, or other power producing gas or fluid, I provide a tank 28 wherein may be stored a reserve supply of the motive agent, and leading from said tank is a pipe 29 to which is rotatably connected the hollow shaft 11. The reserve tank may be dispensed with if desired, in which case the shaft 11 may be connected direct with the source of the motive agent supply, such as an air compressing machine, or other power producing apparatus.

In operating my power transmitting mechanism the motive agent is supplied to the receiving cylinder 14: through the pipe 29 to the hollow shaft 11 and thence through the feed openings 15 thereof into the receiving cylinder which is kept charged with a determined pressure of the motive agent whereby the pistons 26 may be under a constant pressure of the motive agent and which serves to keep said pistons seated against the heads of the auxiliary cylinders 22. The receiving cylinder 1a is then r0- tated by the power from the electric motor 21 and the istons 26 will tend to be unseated from the heads of the auxiliary cylinders 22. The resistance thereby created by reason of the pressure of the motive agent in opposition to the force tending to unseat the pistons 26 will cause sufficient leverage to bear upon the cranks 27 to drive the shaft 11 at the same speed as the receiving cylinder 14.

In the foregoing description I have embodied the preferred form of my invention, but I do not wish to be understood as limiting myself thereto, as I am aware that modifications may be made therein without departing from the principle or sacrificing any of the advantages of this invention, therefore I reserve to myself the right to make such changes as fairly fall within the scope thereof.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1.
